The only time you can call youself short is when your legs don't reach the ground when standing up. Yes it is usually the bigger guys who pick on the smaller ones, no ones picks a fight against someone who they think they cannot beat up..and size does give some advantage.(smaller guys, can only see one way to run). We must accept our own heights,make it work to our advantage,try to be stronger,quicker,and defend ourselves smarter,(running works great). Hands up always(thinking stlye works good-unassuming),talk your way out,Sorry can I buy you another soda? keep your distance. be ready to hit and run. Don't forget to say out loud ,"I am not looking for trouble" in case police comes. It does not take great heights to do those smart things....just a bigger brain...5' people can still poke a 6'3' inch guy in eyes and strike the groin....My thoughts on small stuffs.....Shrimps are good eating...the Hawaiian shrimps....Aloha
